Luxe real estate gets Hollywood treatment

CNBC's Robert Frank speaks to Ryan Serhant of Bravo's "Million Dollar Listing New York," about using highly produced films to sell high-end homes. Serhant recently made a movie about a $23 million penthouse in New York.

It's got romance, mystery, sex appeal and sweeping shots of New York City. But this trailer isn't promoting a new movie. It's pushing a multimillion-dollar penthouse.

Ryan Serhant, a media-savvy Manhattan real-estate broker and a star on Bravo's "Million Dollar Listing New York," has just launched a teaser video promoting his listing of a $23 million penthouse in downtown Manhattan. The video shows a young couple going from a restaurant to a helicopter to a Ferrari, before winding up in the penthouse.

The video is unusual since it doesn't show you actual pictures or scenes of the penthouse (you'll have to see it yourself). Yet the production is part of a new trend in high-end home sales: highly produced mini-movies.

In Los Angeles, broker Mia Trudeau spent thousands to make a $64-million listing look like a scene from a Martin Scorsese trailer.

The marketing of high-end homes has reached a new level -- highly-produced films featuring drone cameras, actors, and even plot lines. We talk to Ryan Serhant, of "Million Dollar Listing" Fame, about a new movie he's made about a $23 million penthouse in New York. It's good hype, but do rich people really buy homes based on a slick reel? CNBC's Robert Frank reports.
